Common Wire Style Dog Crate: How to attach to the side door -wire crate with small wire size of 1/8" #1. Place bracket high enough on the wire door so it can swing open & close and not hit the lower cage wires. #2. Use the short hook bolt to attach the bracket to the cage door. Slide hook bolt through the hole, Hook the cage wire between the bolt and bracket as marked by yellow arrow. #3. Thread on the wing nut at the front of the bracket. Have the bottom of the bracket resting just down past a cross wire support. This keeps the bracket flat against the cage and does not allow twisting, (see marked cross wires) Tighten the wing nut securely in place. Attach the bowl to bracket.
